65% win vs 80% win

[ams16]

Is there any way to make 65% of cities the default win condition for creating new games, rather than 80%? I find that games are pretty much won when someone has 65%, but some people want to play it out until 80%.

I would prefer that the default was 65%. If someone wants a game to go to 80%, that's fine, but make the default 65%.

(I've been in a game where I've been above 70% for a number of turns, but my opponents don't seem to want to quit. It's a slow map, so it's taking a while to consolidate. And I'm bored of it, but I'm not going to stop playing, since I've won.)
